AI-generated listing videos: what an estate agent must disclose in the EU

What changed on 2 August 2026

The transparency obligations of the EU AI Act (Regulation (EU) 2024/1689) became applicable on 2 August 2026. They apply to AI-generated images, audio and video regardless of how small the business publishing them is - there is no exemption by company size, only a reduction in the maximum fine.

For real estate this matters more than for most sectors, because a listing video is a realistic depiction of a real, existing place - exactly the category the rules are written for.

The duty is split, and the visible half is yours

The Act separates two roles. The provider is whoever supplies the AI system. Under Article 50(2) the provider must mark outputs in a machine-readable format, detectable as artificially generated or manipulated. That is metadata and signed credentials - invisible to the viewer.

The deployer is whoever uses the system and puts the result in front of people. Under Article 50(4) the deployer must disclose that the content has been artificially generated or manipulated.

When you upload a generated video to a portal, to Instagram or into your own listing, you are the deployer. No vendor can discharge that duty on your behalf, and a machine-readable tag alone does not satisfy it - a human viewer cannot read metadata.

What "clear and distinguishable" actually requires

Article 50(5) sets the manner and the timing: the information must be provided in a clear and distinguishable manner, at the latest at the time of the first interaction or exposure.

In practice that rules out the two most common approaches: a note at the bottom of a long description, and a disclosure that only appears if the viewer clicks through. Someone scrolling a feed must be able to tell before or as they watch.

• A visible marking in the video frame itself travels with the file when it is reposted or trimmed.
• A line at the start of the listing text, not buried under the specifications.
• The platform's own AI label where one exists - it does not replace your own disclosure, but it does not hurt.

Virtual staging carries a second, older obligation

Furnishing an empty room with AI is not only an AI Act question. Directive 2005/29/EC on unfair commercial practices has prohibited misleading presentations of a product since 2005. Showing a buyer a furnished room that does not exist, without saying so, is capable of distorting their decision - and that is the test the directive applies.

This obligation is older than generative AI and does not depend on it. What changed is the cost of producing such an image: it went from a paid retoucher to a click, so the practice spread fast.

The safe formulation states both facts: that the image is AI-generated, and that the furniture is illustrative and the actual property may differ.

What the penalties look like for a small agency

Article 99(4) sets fines of up to EUR 15 000 000 or 3% of total worldwide annual turnover, whichever is higher, for breaches of the transparency obligations.

There is an important qualification that is easy to miss. Article 99(6) provides that for SMEs, including start-ups, each fine is capped at the lower of the two figures rather than the higher. For a small agency the exposure is therefore the percentage of turnover, not the headline figure - still material, but not existential.

Article 99(7) additionally requires authorities to weigh cooperation, degree of responsibility and steps taken to mitigate. Documented, consistent disclosure is exactly the kind of step that weighs in your favour.

A practical checklist

Everything below is inside your control and takes minutes per listing.

• Keep the visible AI marking in the video. Do not crop it out when resizing for a platform.
• Put one disclosure line at the top of the listing text, in the language of the listing.
• For virtual staging, add that the furnishing is illustrative and the actual property may differ.
• Use the platform's AI toggle where it exists (Instagram, TikTok, YouTube each have one).
• Keep the original file with its credentials intact - it is your evidence of what was generated and when.
• Apply the same rule to photos, not just video. The obligation is about content, not format.

How we handle our side of it

We are the provider, so Article 50(2) is ours. Every video we generate carries a visible marking burnt into the frame for the whole runtime - not only at the start, because a mark shown once is lost the moment the clip is trimmed or reposted. Alongside it the file carries metadata and, where signing is configured, C2PA Content Credentials, which is the interoperable standard the machine-readable requirement points at.

Your side, Article 50(4), we cannot do for you - but we hand you the wording at download time, in the language of the video, ready to paste into the listing.
